Eiki Shiki, Yamaxanadu (四季映姫・ヤマザナドゥ,Shiki Eiki Yamazanadu, given name "Eiki", surname "Shiki") is one of the Yama who judge the dead and decide whether they go to Heaven, Hell, the Netherworld, or get reincarnated. She currently resides in Hell. Whether it's because she simply has a habit of lecturing or because she genuinely wants others to change for the better, she's become well known in Gensokyo for lecturing anyone and everyone about their faults. The souls of the dead are brought to her by Komachi Onozuka, who ferries them over the Sanzu River to Higan. However, not every soul makes it all the way across without being tired out from the journey or being extinguished by Komachi.

Eiki is a yama who belongs to the Ministry of Right and Wrong located at Hell.[1] Although there are many yamas, Eiki is the one in charge of Gensokyo. She, like the other yamas, holds the Cleansed Crystal Mirror that lets them look into a person's past, learn anything they want to know about him/her, and then use that knowledge to make fair judgements.

Eiki does have work breaks, but even during these she doesn't pass up chances to lecture people in the hope that they will change for the better and so she won't have to send them to Hell. For people with particularly bad karma, she will go directly to that person to warn them, sometimes by exaggerating the punishment that they would receive. It's implied that youkai tend to avoid her because of this habit.

Eiki was not always the Yamaxanadu. According to Komachi in Oriental Sacred Place, she was originally a jizou statue, who received enough faith to gain divine powers, and was promoted.

This is as literally stated. With this power, in order to hand down judgements, the charges that have been established once as clear good and evil cannot, no matter what measures the judged person takes, be overturned. The reason why Yukari Yakumo is not good at dealing with Eiki[2] is probably not just because she dislikes preaching, but also because the Yukari that loves chaos and disorder can be said to dislike things to be established as clear good and evil.

Always in Eiki's possession, it can be said to be a rod or a piece of wood. Upon writing the charges on this rod, the weight of the rod changes according to the weight of the sins, and the number of times to beat the sinner is also decided, after which Eiki proceeds to do the beating. This is one of the necessary items for use by Yama for punishment. As explained in Perfect Memento in Strict Sense, she carries this rod with her everywhere.

In the past, each rod was used for one person, and thrown away after its usage was finished. However, for the sake of the environment, it seems that they've been changed to use new material that can be erased and reused.

This is also an item meant for Yama to perform judgement. When a sinner is reflected in the mirror, it reflects all of the sinner's past deeds, though it is tiring to use. It is a dreadful tool for which privacy is even less than worthless, but perhaps because it does not show up in Eiki's sprite, it has a tendency to be forgotten. It can be said that the mirror of the Yama can change shape as they please, but Eiki's mirror takes the form of a hand mirror.

Her full name is Eiki Shiki (四季映姫); Eiki Shiki (using Western name order) would be her romanized name. The kanji for Eiki (映姫) literally means "reflection/projection/casting princess", while Shiki (四季) is the Japanese word for "the four seasons". Her Yamaxanadu (ヤマザナドゥ) title is considered to be a combination of Xanadu (an ancient palace of the Mongol warlord Kublai Khan, which was later used as meaning a "Pleasure Palace" in a poem by Samuel Taylor Coleridge) and her status as Yama, and can mean something along the lines of "Yama of Paradise". This title can be read as "閻魔楽園 (ヤマザナドゥ) ", which has roughly the same meaning as the above.

In the data files for Hopeless Masquerade, Eiki (映姫) was misspelt with the kanji "映季"; the latter kanji means "season". This is a common mistake in the fanbase because the reading of "ki" in 姫 is rarely used, so IME commonly converts it into the former one.

In Phantasmagoria of Flower View's official art, Eiki has blue eyes and green hair that is longer on the right side. She wears a dark blue, black and white dress with gold decorations and one ribbon on both sleeves. She wears a blue and white hat with a gold emblem in front and a red and white bow on the back; the emblem and bow are balanced equally. She also wears black shoes with a red bow on them, and frilly socks. Furthermore, there seems to be a pattern on her uniform that seems balanced and she carries the Rod of Remorse, described above.

Her alternative outfit in Phantasmagoria of Flower View is the same as her usual outfit, but her hat and dress are red, and her white shirt is purple.

Eiki's role was to judge the souls that managed to cross the Sanzu River, but unfortunately couldn't do any major work due to Komachi Onozuka slacking off in the face of the sheer mass of ghosts that were coming through to Gensokyo. Meanwhile, Eiki's interrupted by various residents because they were curious about the huge number of flowers blooming, and Eiki started lecturing them on what negative personalities they've got. She also later researches how many of those people have taken her advice on doing good deeds, in which many of them haven't.

The fairies in Eiki's stage in Phantasmagoria of Flower View are dressed in dark blue uniforms and wear similar hats; and Lily White's normally white dress and hat are colored black. ZUN has said that these fairies and "Lily Black" are all cosplaying as Eiki.[4]

Based on her conversations with the many playable characters in Phantasmagoria of Flower View, she is seen as a compassionate individual, though her conversations with Komachi Onozuka can seem quite harsh. Despite all this scolding, however, Komachi remains a slacker.

She tells Yuuka Kazami to "scare humans" like a regular youkai and tells Reimu Hakurei to "exterminate youkai more." Both of these cases can be simplified to "do your job" and it showed she does not discriminate youkai and human.

The phrase "Eastern Judgement", touhou saiban (東方裁判), in the title of Eiki's music theme is very similar to a Japanese term for the Tokyo Tribunal, Tokyo saiban (東京裁判). The end of World War II and the start of the ensuing tribunal took place 60 years before the events of Phantasmagoria of Flower View, and this similarity in pronunciation is likely intentional.

One of the gods that resides in hell and judges the deceased. She possesses ability to establish things as clear good and evil. Her real name is Eiki Shiki, and the "Yamaxanadu" is a title that she carries in her job as a Yama. Basically the title represents the place they're in charge of.

Unlike humans, she has a criteria of right and wrong in her own mind. Her judgement cannot be overturned by the deceased. Her criteria is quite complicated, and the seriousness of the crimes factor in everything from why they occurred to the personal history of those involved.

The minimum requirement of lying to her, in order to appear as a good person, is not letting her discover that lie. If discovered it is a huge deduction.

Her usual routine is to find faults of the deceased and decide where they will be sent to: Hell, Heaven, or somewhere else. Due to her job, she tends to be somewhat moralistic.

It was when Komachi did not ferry the deceased to her that she noticed something was wrong in Gensokyo. Suspicious, she looked at Gensokyo only to find out that it was blanketed by flowers.

All kinds of flowers were blooming at the same time - spider lilies, sunflowers, lilies of the valley, lotus blossoms, and cherry blossoms. As she was digesting this, both living humans and youkai attacked her, seething with anger.

These assaults immediately made her realize what was going on.
Now it is "that year", 60 years since the previous one.

All these flowers were possessed by spirits of the deceased, and the reason they weren't processed properly was because Komachi was being lazy.
Komachi, being too easygoing, only thought "ah, it's beautiful" even when the flowers were filling the whole place.

It's not like she can restore the flower-covered Gensokyo, but time will eventually bring it back to normal. There was little to no harm.

However, a human who's been charged with a crime is before her. With her pride, she couldn't let her pass through her place.
